Hi All,
 
Don't know if anyone is active here anymore, but recently, I have successfully been able to JTAG a Pace 3100 PVR2. I have already messed around with some colours and background images using a hex editor (https://www.youtube.com/watch?v=IRzyCOJjrjc) - I made 5.07.u look like an older version.
 
However, there are several things that I would also like to know about how the firmware possibly works, with regards to changing the behaviour of the box. Possibly looking at how Sky+ was enabled on the old 4.20.a firmware years back.  
 
For example, as you may be aware, Sky discontinued the EPG Background Audio in 2018, I've been looking at possible methods to change the channel the box uses for this but to no avail.  
 
Thanks!
